I encountered the dreaded rear hub bearing blow out last weekend while practicing at a pretty bumpy track. I noticed after I ran out of gas I picked up my truck and saw my inner hub bearing's outer race on my cvd axle.
These were the factory bearings, I have a complete Boca Bearing Ceramic kit coming and gonna change em' all out before race season starts next week. Its funny I raced all last season and not a single bearing blowout, I have had the truck on the track three times now and a blow out already.
